# Rule Based Chatbot using NLTK
2+
3+
This is a simple rule based chatbot implemented using the Natural Language Toolkit (NLTK) library in Python. The chatbot engages in conversations with users by matching their input with predefined patterns and providing appropriate responses.
4+
5+
## How it Works
6+
7+
The chatbot is built using NLTK's `Chat` class, which allows us to define patterns and corresponding responses. When the user inputs a message, the chatbot searches for a pattern that matches the input and responds with the associated response. If there's no direct match, the chatbot provides a default response to handle any unrecognized inputs.
8+
9+
The predefined patterns cover a range of greetings, questions about the chatbot, jokes, recommendations, and handling user intentions. The chatbot is designed to respond politely and engagingly to various types of user queries.
10+
11+
## Usage
12+
13+
1. Run the `chatbot.py` script, and the chatbot will greet you with a welcome message.
14+
2. Enter your message or query, and the chatbot will respond accordingly.
15+
3. To stop the conversation, simply type `quit` as your input, and the chatbot will bid you goodbye.
16+
17+
## Improving the Chatbot
18+
19+
The predefined patterns can be expanded to make the chatbot more engaging and diverse. In the `chat_patterns.py` file, you can add more patterns and responses to handle a broader range of queries. By doing so, you can reduce the likelihood of default responses and create a more dynamic and interactive chatbot.
20+
21+
## Dependencies
22+
23+
To run the chatbot, ensure you have the following installed:
24+
25+
- Python 3.x
26+
- NLTK library
27+
28+
You can install the required dependencies using pip:
29+
30+
```bash
31+
pip install nltk

# Project Name
2+
3+
This is a simple implementation of the classic game 2048 in Python. The objective of the game is to slide numbered tiles on a grid to combine them and create a tile with the number 2048. The game ends when the grid is full, and no more moves can be made, or when the player successfully creates the 2048 tile.
4+
5+
## How to Play (For Games/Apps)
6+
7+
Initialization: At the start of the game, an empty 4x4 grid is displayed with two randomly placed tiles, each having a value of 2.
8+
9+
Controls: Use the following keys to control the game:
10+
11+
'W' or 'w': Move Up
12+
'S' or 's': Move Down
13+
'A' or 'a': Move Left
14+
'D' or 'd': Move Right
15+
Gameplay: The game progresses with each move in the direction specified by the player. All tiles slide in the specified direction until they reach the grid's edge or collide with another tile of the same value. If two tiles of the same value collide, they merge into a single tile with double the value. After each move, a new tile with a value of 2 is added to the grid at a random empty cell.
16+
17+
Winning Condition: The game is won when a tile with the value of 2048 is created.
18+
19+
Losing Condition: The game is lost when the grid is full, and no more valid moves can be made.
20+
21+
## Features
22+
23+
Basic 2048 gameplay with grid and tile manipulation.
24+
Random tile generation after each move.
25+
Game over and win conditions detection.
26+
Simple console-based interface.
27+
28+
## Technologies Used
29+
30+
Python programming language.
